I sure would like to get some H414 powder for the new 243 AI. Looking at a burn rate chart, W760 and H414 are #109 and #110 respectively. I did my fireforming with 760 and was happy. I could have 'sworn' I had a can of H414, but alas, not in my cabinet.......
I tried every on-line vendor I could think of, but no joy....
